DEPOSITS IN THE CYCLOPROPANE FLOWMETER

Cyclopropane Anæsthesia

TLHIS paper is based on my experience of one thousand cases of cyclopropane anaesthesia personally conducted by me since October, 1938, both in hospital and in private. But before discussing these it might be convenient for me to mention here something about the drug itself. HISTORY. Cyclopropane was first isolated in Germany in 1882 by Freund, who also demonstrated its chemical structure, C 3H...

Cyclopropane Anesthesia

An electromagnetic catheter-flowmeter.

An electromagnetic flowmeter incorporated into a catheter is described. The catheter is introduced into the aorta via the femoral artery. The flow sensor is located some distance below the catheter tip and is sensitive to flow at right angles to the catheter. A crater-like elevation at one end of the transducer lumen permits funnel-like connection of the transducer to the ostium of an aortic br...

YAF: Yet Another Flowmeter

A flow meter generates flow data which contains information about each connection observed on a network from a stream of observed packets. Flow meters can be implemented in standalone measurement devices or inline on packet forwarding devices, such as routers. YAF (Yet Another Flowmeter) was created as a reference implementation of an IPFIX Metering and Exporting Process, and to provide a platf...

The re Structure of Cyclopropane

A long-standing controversy regarding the re structure of cyclopropane is resolved by performing high-level quantum chemical calculations and analyzing the experimental rotational constants for C3H6 and C3H4D2 augmented by calculated vibrational corrections. For the latter, a least-squares fit yields the following set of parameters: re (CC) ) 1.5030(10) Å, re(CH) ) 1.0786(10) Å, and Re(HCH) ) 1...
